Abstract

In this paper an optimized helical antenna is proposed for heating ablation (Hyperthermia) of uterus, ovarian and colon cancers. This antenna is designed in such a way that can be easily insert into the intra cavities, due to its size and flexible shape. Various characteristics of the proposed helical applicator are investigated and optimized for best created specific absorption rate (SAR). After optimizations, the special proposed helical antenna is able to process the maximum symmetry radiation beams and this is an important feature because the cavity which the antenna is located must have capability to heat same in all directions. Finally, measured results of the constructed applicator are presented by the accuracy of simulated results.

腔内热疗应用优化螺旋天线的设计

摘要

本文提出了一种优化的螺旋形天线，用于子宫，卵巢和结肠癌的热消融（体温过高）。该天线以其尺寸和灵活的形状设计成可轻松插入内部腔体。研究并优化了所建议的螺旋施加器的各种特性，以实现最佳的比吸收率（SAR）。经过优化后，提出的特殊螺旋天线能够处理最大的对称辐射束，这是一个重要的特征，因为天线所在的腔必须具有在所有方向上均能加热的能力。最后，通过模拟结果的准确性来展示所构造的涂药器的测量结果。
